Prophalangopsis

Prophalangopsis is a South Asian insect genus, in the family Prophalangopsidae, related to katydids.[1] There is one species: Prophalangopsis obscura, which is a winged insect species found in North India and the Tibetan Plateau. It is one of only a few surviving species in the family Prophalangopsidae. F. Walker described it in 1869 from a single male specimen from India.[lower-alpha 1][1] Liu et al collected two possible female specimens in 2009.[3][4]

Bioacoustic modeling

In 2022, researchers attempted to recreate the call that P. obscura would make with its legs by using 3D scanning, microscopy, and a Laser Doppler vibrometer.[2][5][6]

Notes
  1. Walker identified the location as Hindustan, which is present day India. Sir John Bennet Hearsey, a British army officer stationed in North India, collected the specimen.[2]
